CONDENSER FOR STEAM AND SMOKE.

SPECIFICATION forming part of Letters Patent No. 297,969, dated May 6, 1884;

Application filed September 7, 1883. (No model.) 7

To all whom it may concern:

Be it known that I, JAMES M. CARVER, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certainnew and useful Improvements in Condensers for Steam and Smoke; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the 10 art to which it ap pertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

Figure 1 shows a horizontal section of th machine on the line Y Y of Fig. 3. Fig. 2 is a plan View showing cylinder L, with top plate m partially removed, disclosing the perforated plate 0. Fig. 3 is a vertical section of the entire machine on the line X X,

Fig. 2.

Similar letters refer to similar parts throughout the several views.

Within the cylinder L, made of boiler or 2 5 stackiron, I insert the two pipes A and A, so arranged by suitable gearing, as shown in Fig.

3, that they revolve in opposite directions, each havingv at its base, and at sucha distance from the bottom of the cylinder as to barely pass or shear over the wings a n, cross-pipes B and B, having mitered ends. (Any suit able gearing may be used, that shown in the drawings forming no part of my present invention.) Above and below the said crosspipes are placed the wings or flies n a, made of same or similar metal as the cylinder,those below the cross-pipes being fastened by bolts or other suitable manner to the bottom and sides of the cylinder, and those above the cross-pipes being similarly fastened to the perforated metal plate O,the position of saidwings or flies being shown in Fig. 1. There should be only sufficient space between said flies and the vertical pipes to allow the free passage of water-say half an inch. Said wings should be so placed that the line of their position produced would pass three inches to that side of the center of the pipes A and A, respectively, soonest presenting said wings to the (See Fig. 1.) This position is essential to get the result deed with the boiler and used again.

sired, as thereby the pipes B and B, in' revolving, shear over the wings at an anglewhich best forces the water into the corners formed by the wings and sides of the cylinder, thus facilitating the formation of vacuum. \Vithin the cylinder is also placed the perforated metal plate 0, with perforations c a, the plate resting upon the shoulders of said bottom flies, a n. The cylinder is made tight by the top plate m. The cylinder is connected with the pump or other place of water-supply by the pipe D, thus being filled, when ready for operation, to the outlet E.

I connect the pipe A to the exhaust-pipe of engine by the pipe F,With suitablebearings at G. This for steam. If I desire to condense smoke and not steam, I connect the said pipe A to the Smokestack, using similar bearings.

If I wish to condense both steam and smoke, 7c I use two cylinders. The pipe A,I leave open to the air. When the machine is to be used for condensation of steam only, the cylinder fllled with water above perforated plate 0 is 1 ready for use; but when I desire to condense smoke I add to the water a suflicient quantity of water-lime to thicken the water to the consistency of very thin cream. About three pounds of lime to a barrel of water I find to work the best. This thickening of the water is to retard the passage of the smoke through the water, and thereby perfect condensation.

I do not restrict my claim to the use of water-lime for this purpose. Chloride of lime would answer as well; but water-lime is more economical, because equally effective and V cheaper.

The philosophy of my invention is this, to wit: The revolving of said pipes and crosspipes within .the cylindfl fi i lith watgrpo produces vacuum at the initered ends, and resulting suction, drawing the smoke or steam through the pipes A and B, and discharging the same within the cylinder, where it is condensed by the water, and is discharged at the outlet E, or, in case of steam, may be connect- In like manner air is introduced through the pipe A and cross-pipe B, for the purpose of keeping the temperature of the water in the cylinder 10o below the boiling-point. If air is not furnished in sufficient quantity from the open air, 7

as will sometimes occur in hot weather, I oonneet by suitable bearings with a blower and force it in. The wings or flies n n are for the purpose of breaking up the flow of the water otherwise resulting from the revolving pipes, and the plate 0 is inserted to secure pressure upon the water and steadiness, thus aiding the formation of vacuum as the pipes revolve, and also obstructing the free passage of steam or smoke, thus aiding condensation.

I claim and desire to secure by Letters Patent- 1. In a steam and smoke condenser, the pipes A and A, having cross-pipes B and B, with mitered ends, and revolving in opposite directions, as shown and described.

2. In asteam and smoke condenser, the com bination, with the revolving pipes A and A JAMES M. CARVER.
